CDLL5240A Application Field and Working Principle

The CDLL5240A diode Zener, single device, is a 600 mA glass surface mount device designed for a variety of voltages. It has a wide range of uses, including in electric fuse applications, voltage regulation, and battery chargers.

The CDLL5240A is well suited to many electrical systems. Its high power dissipation in electrical fuse applications helps provide superior electric circuit protection. Its low forward voltage drop eliminates the need for additional components, while its low capacitance voltage clamping helps reduce electromagnetic-interference (EMI). In battery charger applications, it is ideal for use as a zener diode because of its ability to reduce peak current and help maintain constant output voltage.

The CDLL5240A diode Zener, single device, is designed to handle a reverse current of up to 600mA, with a breakdown voltage range from 5.154V to 77.6V. This device is available with a wide range of operating temperature from –55°C to 125°C. It also has a low dynamic impedance of 0.51 ohm/V, ensuring steady-state performance as well as low energy losses.

Working Principle

The CDLL5240A diode Zener, single device, works by allowing a controlled amount of current to flow in the reverse direction of the diode. When the breakdown voltage of the diode is reached, the voltage across the diode increases abruptly, allowing a large amount of current to flow. This current then acts as a short circuit, allowing the voltage regulated output to be maintained.

The CDLL5240A is also designed to have low capacitance, providing improved voltage clamping capabilities and higher immunity to EMI. Low capacitance also helps to keep the current through the device at a lower level, reducing the overall power dissipation. The CDLL5240A allows the output voltage to remain stable even under varying input currents or output voltages, providing excellent regulation and low noise performance.
